BRUSSELS (Reuters) - The leaders of the 27 EU countries remaining in the European Union have agreed to an extension of Brexit, the chairman of EU summits said in a tweet on Thursday.

Donald Tusk, the European Council president, said in his text that he would now be meeting British Prime Minister Theresa May to secure her agreement. Tusk's tweet did not say how long the extension would be, but Reuters earlier reported that it would be until the end of October, with a review in June.
